METAL WHEEL. 1

reason.

Specification of Letters Patent; Patented Jan. 18, 1921.

Application filed May 18, 1918, Serial No. 235,269. Renewed September 18, 1920. Serial N0. 1111.266.

To aZZcv/wm it my concern:

Be 1t known that I, Ronmrr citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and.

State of Ohio, have invented certain new and useful Improvements in Metal Wheels,

of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the arttowhich it appertains, to make and use the same.

The objects of the invention are toprovide an improved form of construction for a sheet metal wheel, by means of which the heavy wooden felly is dispensed with, and thus saving the additional weight atthe out- 3 side and lessening therflywhcel effect of rapld rotation. Also a ventilated rim is produced giving the tire a greater chance to radiate its heat.

The invention comprises a former application Serial No. 142,429 filed Jan. th, 1917 as to the common features, showing a circumferentially divided hub, and integral longitudinally divided spokes, and a felly band and -a demountable rim, superimposed thereon and {also comprises the details of construction, hereinafter described, shown in the accompanying drawings and specifically pointed out in the claims. p p i In the accompanying drawings, Figure 1 is a side elevat on ofthe device,

Fig. 2 is a transverse section" thereof on center line of spokes, I Fig. 3 is a perspective of a portion of the hub, and one spoke illustrating the manner of assembling the parts,

Fig. 4 is a transverse section of'one of the spokes, r V

Fig. 5 is an enlarged section" otthe felly band and rim; 1 a

Fig. 6 is a perspective illustrating the 1n: terlocking constructons of the spokes and showing members before assembling,

Fig: 7 illustrates the use of a single clencher rim,

In these views A, A" represent two halves of a-sheet metal hub, the centers of which are provided with. axial openings B, B one being larger than the other, through which a metal hub D is inserted.

The hub members are stamped from sheet metal plates integrally with members C and C, respectively of the radially arranged Vl niorrr, a

one member overlapping the vGr of the other division of my welding or riveting. The sheet metal hub members overlap at F, F attheir circumferential edges and each edge has ts corrc spondlng semi-cylindrical spoke portion 111- tegrally llormcd therewith unlit illustrated in Fig.6. The sicesof oneof thcspoke members overlap the sides or the opposed spoke member in the manner shown; the edge G of adjacent edge member to make a thoroughly firm jointtherewith. At the outer extremity of each spoke member is shown a transversely extended flange or integral plateH and H 'resoectivelv; These flanges abut against each other at I, I and overlap alternate odgesof the spoke members at J, J.

A telly band or rim member E is sleeved over the spokes and attached flanges and all the overlapping parts are attached together by rivets, electric spot-welding or brazing.

so that one integral structure results, which while light in weight is rigid and is propon tioned to resist lateral and radial strains of all kinds and is easily constructed from sheet metal from dies. l y

The outer rim orband cairbe used directlyas a tire holdingrim, or a demountablc rim L can be superimposed thereon as described in my previous application, Serial No; 142,429, filed Jan." 15th, 1917.

The hub extremities are dished in form to givc added strength and the spokes are hollow and are pre in shape or slightly tapering to give the general appearance of an artillery wheel.

Bolts M, M, secure the inner edges of the hub members together and they are posi tively spaced by moans of spool shaped. sleeves N, N,

ably semicylindrical at their outer extremities, and a metal rim attached tosaid transverselyextending terminal' flanges.

2. In a metal wheel, a. metal hub member provided with spaced shoulders, dished sheet metal hub members sleeved over said metal hub, and resting against said shoul *ders' bolts secur n said dished hub members together, spacing sleeves on said bolts, the circumferential edges of said dished members provided with overlapping inwardly extending annular flanges, opposed 'spoke members'integrall'y attached to said dished members, interlocking flanges upon the: longitud nal edges of said spoke members, abutting laterally extending flanges upon the outer extremities of said spoke members, and a' metallic rim extended over 7, the flangesatthe extremities of said spokes.

1 o 3, Anvheel comprising dished sheet metal nular formation and interlocked with each other.

The combination of dished hub members provided with inwardly extending annular circumferential flanges overlapping each other and provided with interlocking ribs, and spokes carried by the hub members.

111 testimony whereof, I hereunto set my 35 hand this 23rd day of April 1918.
